Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. (ERG, 2016)

10.3 Possibility of hazardous reactions

Attacks plastics. [Handling Chemicals Safely, 1980. p. 236]. Acetyl bromide reacts violently with alcohols or water [Merck 11th ed. 1989]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: An explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid [Chem. Eng. News 45(43):73. 1967; J, Org. Chem. 28:1893. 1963]. Alkyl hypochlorites are violently explosive. They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. Chlorine plus alcohols would similarly yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M. 1991]. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

12.2 Persistence and degradability

In an aerobic, sewage die-away screening test alpha-methylbenzyl alcohol (at 6000 ppm) biodegraded rapidly with 78.2% of the theoretical BOD reached in 8-10 days(1). Phenol-adapted cultures grown without alpha-methylbenzyl alcohol, with alpha-methylbenzyl alcohol (at 100 mg/L), and with both phenol and alpha-methylbenzyl alcohol consumed 69, 75, and 320 ul O2, respectively, over a 210 minute period(2). An Arthrobacter strain initially dehydrogenates alpha-methylbenzyl alcohol to acetophenone which is then converted to an ester, producing phenyl acetate which is then hydrolysed to phenol and acetate(3). A Nocardia strain first oxygenates the benzene nucleus to give 3-(1'-hydroxyethyl)-3,5-cyclo-hexadiene-1,2-diol which is then reduced and subjected to extra-diol cleavage(3). This same strain is also able to degrade alpha-methylbenzyl alcohol using the same pathway as described above for Arthrobacter(3). Alpha-methylbenzyl alcohol, inoculated with a mixed microbial culture, was readily biodegraded from 550 ppm to 20 ppm over 32 days(4). Nitrosomonas europaea degraded 2.5% of alpha-methylbenzyl alcohol (initially present at 200 nmol) over a 15 hour period(5). Alpha-methylbenzyl alcohol had a BOD of 1.0 g/g alpha-methylbenzyl alcohol after a 10 day incubation with a sewage inoculum(6).

12.3 Bioaccumulative potential

An estimated BCF value of 9 was calculated for alpha-methylbenzyl alcohol(SRC), using a measured water solubility of 1950 mg/L at 25°C(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will not be an important fate process(SRC).

12.4 Mobility in soil

Koc values for alpha-methylbenzyl alcohol were determined for three subsoils: Apison (organic content = 0.11%) had a Koc of 37, Fullerton (organic content = 0.06%) had a Koc of <5, and Dormont (organic content = 1.2%) had a Koc of 52(1). According to a recommended classification scheme(2), these Koc values suggest that alpha-methylbenzyl alcohol has very high mobility in soil, although increasing organic content will act to reduce mobility slightly(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
